Well my thread about it !
200$ paid, Friday after noon i'm on it!
Here's my final scores on the Boson Ex-Sim max since December 16. My first score was very BAD.
I started reading the Route book in November for reviewing a bit for my CCNA exam on December 9th for routing protocols and then when my ccna completed, i've moved completly to that new stuff and to be honest, i LOVED reading this book and practicing all those concepts.
Now it's time for the real exam !!!

I've just finished the 157 questions including about 6-7 labs and now i feel very confident. The labs are a bit dumb because when you get 1 error, you fail the lab.
I think Cisco grade you command by command or something like this, but i'm not 100% sure.
